Is the Number Prime or Composite

Level 1

This math topic focuses on determining whether a given number is prime or composite. It's aimed at helping learners identify the factors of a number and distinguish between prime numbers, which have only two distinct positive divisors (1 and the number itself), and composite numbers, which have more than two divisors. The topic includes a series of problems where learners must classify specific numbers (e.g., 27, 60, 21, 35, 31, 26, 29) as either prime or composite. This set of problems is part of an introductory unit on factoring and primes.
